"My wife and I bought a house a couple years ago, and became owners of a radiant heating systems installed more than 20 years ago. Tony and Damian did a great job of understanding how my radiant heating system works, what repairs were needed/what was failing, and where upgrades were needed. They replaced the pump, both expansion tanks, and the neutralizer. Additionally, they noticed the hot water tank was installed incorrectly, and the hot and cold water connections were flipped. It's amazing the system worked, and it's nice to have a system that's correctly installed (even if it's 20 years later!). Additionally, they secured the expansion tanks to the wall (now required by code), replaced the deteriorating copper pipes connected to the neutralizer with plastic (I'm sure this is code now as well), and re-routed the overflow pipes to the outside (rather than the floor!). You can't go wrong with these guys, well done, they're true craftsmen to the trade."

"Dennis is a good guy and a professional. He showed up promptly on time. Analyzed the problem as my heater's thermostat failed. He had a replacement part, ready to go but it wasn't WiFi capable. I decided to get a smart thermostat from Best Buy and asked him to return to install it. He did and my furnace is heating my humble little house. Thank you Dennis, job well done. "

"We did a major renovation in our house and replaced the old gas heating system. Bobby did a great job of installing the new heat-pump based central A/C unit. He picked the right unit for our house and installed it along with all the ducts. He's also easy to reach to for any questions or maintenance requests. We've been using the system over a year and it's running great."

"Install draft inducer and installed carbon monoxide det. Did an excellent job."

"Jim's Air Systems had the best value for my dollar. They supplied me with better equipment than they quoted for the same price. They completed the entire installation in about five hours. They protected my floors with tarps and were very careful to protect my walls as they moved equipment in and out. Josh, the son of the original Jim, was on the job working with the other two installers. They performed above my expectations. They left my home and yard as clean as if they had never been there. The new furnace is wonderful and is already saving me money on my P.G. & E. bill. I would recommend Jim's Air Systems unconditionally to anyone in need of a new furnace and AC system. This is a family business that has been supplying and installing systems since 1976. They take personal pride in doing an excellent job. They did not sell me anything that I did not need and provided me with a much cleaner and easier-to-service installation than my existing system. They are the best! "

"My HVAC unit was 20 years old needed consistent repair, and my ducks where leaking. It was time for a new unit. I also wanted to relocate the condenser to improve my back yard space. I had gotten 4 quotes before someone referred me to http://www.aircmechanical.com/ Vitor was literally the first smart person to offer a quote. He suggested relocating the condenser to a side of the house and changing it to a suitcase type unit. He also came up with the creative solution of adding a 2nt inlet in another part of the house to reduce noise and improve airflow. The other contractors wanted to enlarge and or relocate the existing inlet which would have been an ugly mess. I now have an extremely efficient 2 stage unit installed correctly and he beat the other quotes. Entire product was completed in 2 days. I couldnâ t be happier."

"Joy was great in fixing our furnace and replacing our old thermostat. He provided tips if we decide to add an AC in the future. Highly recommend!"
